2012年巴菲特致股东的信

2012年巴菲特致股东的信（重点节选）投资往往为被描述为这样一个过程，现在投入一些钱，希望未来能收回更多的钱。

在伯克希尔哈撒韦，我们采用更高的标准，将投资定义为“现在将购买力让渡给他人，合理期待未来支付名义收益税率后，仍能获得更高的购买力”。

简言之，投资就是放弃现在的消费，以便将来有能力消费更多。

从我们的定义可以得出一个重要结论：衡量投资风险高低的指标不应是贝塔值一个基于波动率的华尔街术语，常用于衡量风险，而是持有期满后投资人出现购买力损失的合理概率。

资产价格可能大幅波动，但只要有理由肯定投资期满后它们带来的购买力能得到提升，这项投资就没有风险。

稍后我们还会看到，价格没有波动的资产也可能充满风险。

投资选择林林总总，但大体可分为三类，理解每一类的特点很重要。

下面，我们将展开详细的分析。

市场上以特定货币结算的投资包括货币市场基金、债券、按揭、银行存款和其他工具。

大多数此类投资都被视为“安全”，但事实上却是可能属于最危险的资产。

它们的贝塔值可能是零，但风险巨大。

上个世纪，这类投资工具摧毁了很多国家投资者的购买力，尽管投资者一直能够按时收到支付的本息。

而且，这样的糟糕结果将来还会不断重现。

政府决定货币的最终价值，而系统性力量有时会推动它们制定导致通胀的政策。

这些政策一不留神就会失控。

即使是在美国，政府强烈希望维持本币稳定，但是，我1965年接管伯克希尔哈撒韦以来，美元也已贬值高达86%。

当年花1美元能买到的东西，今天至少要花7美元。

因此，这些年来，一个免税机构须取得4.3%的债券投资年收益，才能保持购买力不变。

假如管理层还将一切利息收入视为“收益”，他们一定是在开玩笑。

对于像你我这样的应税投资者，情况就更糟了。

过去的47年里，美国国债不断地滚动，年回报率5.7%。

听起来好像还不错。

但对于个人所得税率平均为25%的的个人投资者而言，这5.7%的回报率所能带来的实际收益是零。

投资者缴纳的、可见的所得税将拿走上述回报率中的1.4个百分点，通胀因素这个隐形的“税种”将吞噬其余4.3个百分点。

值得指出的是，尽管投资者可能认为显性的所得税是主要的负担，但其实，隐形的通胀“税”是所得税的3倍还多。

没错，每张美元上都印着“我们信仰上帝”这句话，但启动美国政府印钞机的是凡夫俗子的手。

当然，高利率能弥补依托于货币的投资工具所带来的通胀风险。

而且，20世纪80年代初时的利率确实很好地做到了这一点。

不过，要抵消消费者购买力面临的风险，当前的利率水平还差得远。

因此，眼下应谨慎投资债券。

By Warren BuffettInvesting is often described as the process of laying out money now in the expectation of receiving more money in the future. At Berkshire Hathaway (BRKA) we take a more demanding approach, defining investing as the transfer to others of purchasing power now with the reasoned expectation of receiving more purchasing power -- after taxes have been paid on nominal gains -- in the future. More succinctly, investing is forgoing consumption now in order to have the ability to consume more at a later date.From our definition there flows an important corollary: The riskiness of an investment is not measured by beta (a Wall Street term encompassing volatility and often used in measuring risk) but rather by the probability -- the reasoned probability -- of that investment causing its owner a loss of purchasing power over his contemplated holding period. Assets can fluctuate greatly in price and not be risky as long as they are reasonably certain to deliver increased purchasing power over their holding period. And as we will see, a nonfluctuating asset can be laden with risk.Investment possibilities are both many and varied. There are three major categories, however, and it's important to understand the characteristics of each. So let's survey the field.Investments that are denominated in a given currency include money-market funds,bonds,mortgages, bank deposits, and other instruments. Most of these currency-based investments are thought of as "safe." In truth they are among the most dangerous of assets. Their beta may be zero, but their risk is huge.Over the past century these instruments have destroyed the purchasing power of investors in many countries, even as these holders continued to receive timely payments of interest and principal.This ugly result, moreover, will forever recur. Governments determine the ultimate value of money, and systemic forces will sometimes cause them to gravitate to policies that produce inflation. From time to time such policies spin out of control.Even in the U.S., where the wish for a stable currency is strong, the dollar has fallen a staggering 86% in value since 1965, when I took over management of Berkshire. It takes no less than $7 today to buy what $1 did at that time. Consequently, a tax-free institution would have needed 4.3% interest annually from bond investments over that period to simply maintain its purchasing power. Its managers would have been kidding themselves if they thought of any portion of that interest as "income."For taxpaying investors like you and me, the picture has been far worse. During the same 47-year period, continuous rolling of U.S. Treasury bills produced 5.7% annually. That sounds satisfactory. But if an individual investor paid personal income taxes at a rate averaging 25%, this 5.7% return would have yielded nothing in the way of real income. This investor's visible income tax would have stripped him of 1.4 points of the stated yield, and the invisible inflation tax would have devoured the remaining 4.3 points. It's noteworthy that the implicit inflation "tax" was more than triple the explicit income tax that our investor probably thought of as his main burden. "In GodWe Trust" may be imprinted on our currency, but the hand that activates our government'sprinting press has been all too human.High interest rates, of course, can compensate purchasers for the inflation risk they face with currency-based investments -- and indeed, rates in the early 1980s did that job nicely. Current rates, however, do not come close to offsetting the purchasing-power risk that investors assume.Right now bonds should come with a warning label.Warren Buffett: Your pick for Businessperson of the YearUnder today's conditions, therefore, I do not like currency-based investments. Even so, Berkshire holds significant amounts of them, primarily of the short-term variety. At Berkshire the need for ample liquidity occupies center stage and will never be slighted, however inadequate rates may be. Accommodating this need, we primarily hold U.S. Treasury bills, the only investment that can be counted on for liquidity under the most chaotic of economic conditions. Our working level for liquidity is $20 billion; $10 billion is our absolute minimum.Beyond the requirements that liquidity and regulators impose on us, we will purchasecurrency-related securities only if they offer the possibility of unusual gain -- either because a particular credit is mispriced, as can occur in periodic junk-bond debacles, or because rates rise to a level that offers the possibility of realizing substantial capital gains on high-grade bonds when rates fall. Though we've exploited both opportunities in the past -- and may do so again -- we are now 180 degrees removed from such prospects. Today, a wry comment that Wall Streeter Shelby Cullom Davis made long ago seems apt: "Bonds promoted as offering risk-free returns are now priced to deliver return-free risk."The second major category of investments involves assets that will never produce anything, but that are purchased in the buyer's hope that someone else -- who also knows that the assets will be forever unproductive -- will pay more for them in the future. Tulips, of all things, briefly became a favorite of such buyers in the 17th century.This type of investment requires an expanding pool of buyers, who, in turn, are enticed because they believe the buying pool will expand still further. Owners are not inspired by what the asset itself can produce -- it will remain lifeless forever -- but rather by the belief that others will desire it even more avidly in the future.The major asset in this category is gold, currently a huge favorite of investors who fear almost all other assets, especially paper money (of whose value, as noted, they are right to be fearful). Gold, however, has two significant shortcomings, being neither of much use nor procreative. True, gold has some industrial and decorative utility, but the demand for these purposes is both limited andincapable of soaking up new production. Meanwhile, if you own one ounce of gold for an eternity, you will still own one ounce at its end.What motivates most gold purchasers is their belief that the ranks of the fearful will grow. During the past decade that belief has proved correct. Beyond that, the rising price has on its own generated additional buying enthusiasm, attracting purchasers who see the rise as validating an investment thesis. As "bandwagon" investors join any party, they create their own truth -- for a while.Over the past 15 years, both Internet stocks and houses have demonstrated the extraordinary excesses that can be created by combining an initially sensible thesis with well-publicized rising prices. In these bubbles, an army of originally skeptical investors succumbed to the "proof " delivered by the market, and the pool of buyers -- for a time -- expanded sufficiently to keep the bandwagon rolling. But bubbles blown large enough inevitably pop. And then the old proverb is confirmed once again: "What the wise man does in the beginning, the fool does in the end."Today the world's gold stock is about 170,000 metric tons. If all of this gold were melded together, it would form a cube of about 68 feet per side. (Picture it fitting comfortably within a baseball infield.) At $1,750 per ounce -- gold's price as I write this -- its value would be about $9.6 trillion. Call this cube pile A.Let's now create a pile B costing an equal amount. For that, we could buy all U.S. cropland (400 million acres with output of about $200 billion annually), plus 16 Exxon Mobils (the world's most profitable company, one earning more than $40 billion annually). After these purchases, we would have about $1 trillion left over for walking-around money (no sense feeling strapped after this buying binge). Can you imagine an investor with $9.6 trillion selecting pile A over pile B?Beyond the staggering valuation given the existing stock of gold, current prices make today's annual production of gold command about $160 billion. Buyers -- whether jewelry and industrial users, frightened individuals, or speculators -- must continually absorb this additional supply to merely maintain an equilibrium at present prices.A century from now the 400 million acres of farmland will have produced staggering amounts of corn, wheat, cotton, and other crops -- and will continue to produce that valuable bounty, whatever the currency may be. Exxon Mobil (XOM) will probably have delivered trillions of dollars in dividends to its owners and will also hold assets worth many more trillions (and, remember, you get 16 Exxons). The 170,000 tons of gold will be unchanged in size and still incapable of producing anything. You can fondle the cube, but it will not respond.Admittedly, when people a century from now are fearful, it's likely many will still rush to gold.I'm confident, however, that the $9.6 trillion current valuation of pile A will compound over the century at a rate far inferior to that achieved by pile B.Our first two categories enjoy maximum popularity at peaks of fear: Terror over economic collapse drives individuals to currency-based assets, most particularly U.S. obligations, and fear of currency collapse fosters movement to sterile assets such as gold. We heard "cash is king" in late 2008, just when cash should have been deployed rather than held. Similarly, we heard "cash is trash" in the early 1980s just when fixed-dollar investments were at their most attractive level in memory. On those occasions, investors who required a supportive crowd paid dearly for that comfort.My own preference -- and you knew this was coming -- is our third category: investment in productive assets, whether businesses, farms, or real estate. Ideally, these assets should have the ability in inflationary times to deliver output that will retain its purchasing-power value while requiring a minimum of new capital investment. Farms, real estate, and many businesses such as Coca-Cola (KO), IBM (IBM), and our own See's Candy meet that double-barreled test. Certain other companies -- think of our regulated utilities, for example -- fail it because inflation places heavy capital requirements on them. To earn more, their owners must invest more. Even so, these investments will remain superior to nonproductive or currency-based assets.Whether the currency a century from now is based on gold, seashells, shark teeth, or a piece of paper (as today), people will be willing to exchange a couple of minutes of their daily labor for a Coca-Cola or some See's peanut brittle. In the future the U.S. population will move more goods,consume more food, and require more living space than it does now. People will forever exchange what they produce for what others produce.Our country's businesses will continue to efficiently deliver goods and services wanted by our citizens. Metaphorically, these commercial "cows" will live for centuries and give ever greater quantities of "milk" to boot. Their value will be determined not by the medium of exchange but rather by their capacity to deliver milk. Proceeds from the sale of the milk will compound for the owners of the cows, just as they did during the 20th century when the Dow increased from 66 to 11,497 (and paid loads of dividends as well).Berkshire's goal will be to increase its ownership of first-class businesses. Our first choice will be to own them in their entirety -- but we will also be owners by way of holding sizable amounts of marketable stocks. I believe that over any extended period of time this category of investing will prove to be the runaway winner among the three we've examined. More important, it will be by far the safest.。
